Hi, I just put together my first system with the following specs:

CAS: Antec Three Hundred
GFX: Radeon HD 4870
CPU: Phenom II X3 720
MOB: Gigabyte GA-MA770T-UD3P
MEM: Mushkin DDR3 PC3-1333 4GB
PSU: Corsair VX550W
DVD: WriteMaster SH-S223F
HD1: Samsung SpinPoint F1 Desktop Class HD502IJ 500 GB
HD2: Samsung SpinPoint F3 Desktop Class HD502HJ 500 GB

It started up fine, I set up the raid and started installing windows.
It did the BIOS look-a-like part, and was working on the windows installation when poof.
When I turn it on, fans move for about half a second, and then turn off.
I've tried taking out all components except for the mobo, cpu and psu, and it's the same result.

Please, does anyone know what might be wrong?
 
Do you have a case speaker/buzzer installed?
Do you get error beeps with no RAM?
Do you get error beeps with no Vidcard?
Do you get error beeps with no RAM nor Vidcard?
Have you tried clearing your CMOS?
Have you done a barebones bench test outside of the case as outlined in the Basic Troubleshooting Guide Sticky thread?
Do you have a surge protector?
Does the PSU pass the paperclip test as briefly described in the basic troubleshooting guide?
Have you tried it with only one stick of RAM installed?
Have you tried re-seating your CPU?
 
Hi,
No case speaker
No error beeps at all
CMOS cleared
Barebones test done
No surge protector, but the connection is grounded
I actually don't have a paperclip or anything that could substitute, but I'm trying to get one today.
Tried with 1 RAM
Haven't tried reseating the CPU, I don't have any additional thermal paste.
Did everything in the basic troubleshooting guide.

But even if the CPU was off, shouldn't the system at least turn on?

Thank you
 
Did you wear an ESD wristaband?
Was it assembled on carpet?
Did you check the PSU (multimeter)?
Are any of the cables not seated correctly/burnt out?
 
Do idea what an ESD wristaband is.
It was assembled on a mixture of a carpet and a chair, depending on the height I needed it to be in (guess I should have thought about that).
Haven't checked the PSU and I can't check the PSU yet, as I have no tools. No paperclip or multimeter.
All cables are fully inserted.
 
This is an ESD wristband, which is also known as an anti-static wrist strap. It can help reduce the chances of static killing your components, especially if you've grounded yourself properly before you started working on your computer (or even opening it up).

Working on the carpet is a good way to generate static, but without any tools, there's no way to be certain whether or not anything was affected. Even then, static is tricky to predict: it can "linger" inside a computer part and shorten its lifespan just as easily as it instantly kill the part.

Have you looked that the basic troubleshooting sticky? If not, check it out... and get a couple of tools along the way.

If there's no case speaker, then how would you hear the beeps? :eek: :confused:

:p

Get a case speaker so you can hear the POST error beeps -- this is the main diagnostic means of communication for your mobo.

You obviously didn't do everything in the guide, because you stated you didn't try a couple things which are in the guide. :p

What do you mean by the CPU being "off" and the system turning on?

Did you do the barebones benchtest outside of the case, on the cardboard box as described in the sticky? If not, something in the case may be grounding/shorting out your board.

Did you try it with no vidcard? For this to be helpful, you'll need a case speaker. So again, get one.
 
Well, the motherboard can have one built in.
I remember I used to have these 1" diameter 'beep' speakers for industrial PC setups I had (Intel mobo).
 
Yes, the case speaker could be onboard! I should add that bit of info to the Basic Troubleshooting Guide Sticky! Oh wait, its already there. :p :D ;) </sarcasm> ... must be getting late... i'm getting irritable.
 
I went to a mates place and tried out my PSU on his system (which takes less wattage than mine), and it had the exact same result, so I'm returning my PSU and getting a new one.

When I say it doesn't have a speaker, it's because there's no sound, there's no POST either.
 
more than likely the mobo is faulty, even if it is brand new. similar thing happened to me with your described symptoms (whole system functioned and then just stopped working for no apparent reason, and all system fans spun for less than a second, just like yours...mobo power led still lit and all other components tested as functional with barebones testing) - all i did was swap out for an identical board and poof - system worked. so as far as troubleshooting, i would recommend swapping out the mobo before trying anything else, assuming you already covered the basics.
 
I'd recommend simply getting a speaker/buzzer attached before swapping out the board. Without the speaker, you can't tell if its bad ram or bad vidcard unless you try them in another board. Your mobo does not have an onboard system speaker/buzzer. If your case has one, you would have plugged it into your front panel header (see mobo manual for details). You really need to get one to properly diagnose your problems.

No worries jeremy, I was just irritable last night. :(
 
Well unlike with your case, I never got a light on, there was nothing, as if the system had never been turned on. The motherboard does have a speaker (according to the manual), but it hasn't said anything.

However, this new PSU... Is running perfectly fine, I had a long lunch break, bought a PSU, installed it, and left the computer running when I went back to work. So, of it's still running (or at least still working) when I get home, then it's definitely a case of bad PSU. If the PSU is once again broken, there's something else awry (the first PSU was from a different shop, and a different line of PSU).

Thank you for your support so far :)
 
Your Corsair VX550 should still be under warranty. If the replacement PSU isn't as good quality as the Corsair, I'd RMA the Corsair and sell/return the replacement PSU. Which replacement did you buy?

Also, according to your mobo manual, there is NO onboard speaker/buzzer. Page26 for the Gigabyte GA-MA770T-UD3P shows a header to plug in a case speaker, but no onboard speaker. :confused: When you startup your computer, this is the buzzer/speaker that gives the standard single POST beep, letting you know of a successful POST.

k, a bad psu would have been my guess in the case of no light.

Corsair HW520W, from a different store :)
It's working brilliantly, and has been running for nearly 24 hours now.
